The M-diag Bluetooth OBD II car diagnostic tool is just one example of many dongles that do this, but after careful examination of customer reviews online, I selected this model because it seemed to be one of the best models out of the bunch with the highest amount of satisfied customers. While compare to other Bluetooth diagnostic tool, M-diag has Attractive advantage shown below:
You can find online Launch easydiag 2.0 for $59 only has four diagnostic systems
Golo Easydiag+ is much powerful with full system diagnosis, but it’s much expensive too. ($120 at ebay)
Now M-diag is also $59 for full system diagnosis as well as special functions, actuation tests.
Overall, the $59 investment between the iOS OBDII scanner and the App seems to be a worthwhile alternative to the clunky scanner. It’s really cool to see that you can use your iPhone to read a kind of live data, and it’s a great way to ensure your car is in good health.
